Come on, cloud storage? Why bother with cloud storage when one will have pentabytes in a thumbnail-sized chip? I would never use cloud storage in a pink fit. Trust Microsoft, Google, et al with my data. Not likely.

And why use a phone and locked-in apps? I suggest you read how I use my phone now, in 20 years I'll have even more control over my data: https://news.ycombinator.com/context?id=35243759

Also check my comment underneath in reply to a commentator.

You're obviously of the smartphone generation, I'm pre that so I think outside that box. In 20 years things will be very different and that doesn't necessarily mean that Big Tech will still rule the roost.
